Ok...
Door Vin Plate "B-4-TA 190"...
B= B series Truck
4= year (1953)
T= 3 Ton Rating
A= 2 Speed Rear Axle (Timkin Double Reduction)
190= 190" WB
As for the "T" series trucks they originally came with the 331ci T322 engine.....3-3/4" bore X 5" stroke.
Your fire engine truck has a
T324-3337 engine.
That T324...engine is a designated 4 ton truck engine that first came out in 1951 and was used through 1953.
The T324...engine was used in the biggest of the Dodge truck line "Y" series trucks.
But now...Gets a little sticky.
That T324..engine from 1951 thru 1952 is a 377ci. 4" bore X 5" stroke.
The T324.. engine starting in 1953 had a bore and stroke increase to make it a 413ci.
4-1/16" bore X 5-5/16" stroke.
The only easy way to see which T324.. engine is in the fire engine (377 or 413) And how to do that is to remove the 7/16" hex plug over #6 cylinder and measure the piston stroke using a straight piece of say 1/8" steel rod.
Remove the hex plug...set 10"-12" rod down hole to piston top.
Remove all spark plugs so the engine will turn over easily by turning the fan (fan belts need to be tight) or use thumb to keep belt tension while turning fan.
Measure the total up/down rod travel while rotating the engine using the fan.
5" is a 377ci.
5-5/16" is a 413ci.
That engine will run just fine...
The Moly Block engines are serious heavy duty engines.
Change the oil and filter.
Clean and rebuild the Ball and Ball carbs....easy to get the carb kits...
Could be E7U1 or 2
E9G1..
NAPA/O'Reilly's even has the kits..I just bought two kits for a 413 I did carbs on.
Points, condensor.... All I will say don't buy new from a parts store...Chinese junk. I would just to get it up and running carefully clean the existing points..set to .020" check the cap and rotor...it will fire right up.
Fuel pump and tank will be a problem...get the pump rebuilt with a ethanol resistant diaphram etc.
Gad tank....well look at it clean it...do what it needs to be real clean and rust free.
There is plenty more to get caught up on needed maintenance....let others offer up on that.
Looks like that truck has hydraulics with the double bladder brake booster...didn't see a air compressor.
That's another story there!
Good to see the engine given new life!
